  }


layer.setMap(map);   
google.maps.event.addListener(layer, 'click', function(e) { 

alert(JSON.stringify(e, null, 4)); //UNDIFINED not Working

  var lati = e.latLng['mb'];  
  var lng = e.latLng['nb'];  
  var x = e.row['id_witel'].value;
  get_details('w',e.row['id_witel'].value,lati,lng);    
});


}

thank's for any help

Answer 1

There are no "official" properties mb and nb for a google.maps.LatLng(that's what e.latLng is) . These properties will be used internally by the API, the names of these properties may change the next moment, hour or day.

To retrieve latitude and longitude use the methods lat() and lng() of e.latLng
